Iimpawu eziphambili ze-aluminium foam acoustic panels:
I-1, itekhnoloji ephezulu, ipleyiti yealuminiyam edibeneyo edibeneyo, ukusebenza kakuhle kwe-acoustic, isithintelo se-acoustic, ubunzima obulula, intle, ingenamlilo, ingoyiki amanzi, iipropathi ezilungileyo zomzimba, ukusetyenzwa ngokulula, ezenziwe ngayo kwiintlobo ezahlukeneyo zomzimba ofunxa isandi, i-muffler. , isakhiwo sokugquma isandi, isithintelo sesandi, igumbi le-muffler, i-insulation insulation cover, njl., Inokujongana ngokuthe ngqo nomthombo wengxolo, ngaphandle kwayo nayiphi na ipaneli yokukhusela kunye nezinye izandi ezifunxa izandi.
2, Inentsebenzo ebalaseleyo ye-acoustic: i-coefficient yokufunxa isandi ≥0.60 (125-4000Hz uluhlu lwamaza); okwangoku, inomsebenzi obalaseleyo we-acoustic ukuba ukusebenza kwesandi sokufunxa akutshintshi emva kokutshiza amanzi kunye nokutshiza umlotha ebhodini.
I-3, ipleyiti ye-aluminiyam yogwebu nge-aluminium alloy die-casting molding, eyaphukileyo, inokuphinda isetyenziswe, okwangoku akukho lungcoliseko lwesibini kwimo engqongileyo yeemveliso eziluhlaza eziphezulu.

Iziphumo zokuvavanya ukusebenza kwephaneli ye-aluminium foam acoustic
■ Iimpawu zePore kunye nokuxinana kwesambuku
Ubungakanani bepore obuphambili: 0.9mm, 1.6mm, 2.5mm iinkcukacha ezintathu, iinkcukacha ezisetyenziswa ngokuqhelekileyo kwi-1.6mm pore size.
I-Porosity: 60-80% (68-78% kwi-1.6mm ubukhulu bepore)

I-NRC yokunciphisa ingxolo” 0.64 (250-2000Hz umlinganiselo woluhlu lwamaza)
■ Ukusebenza kokufakelwa kwesandi: kulinganiswa nge-GBJ75
Isandi somoya esinobunzima bokugquma isandi Rw 28.0dB (okt isalathiso sokugquma isandi la)
I-avareji yokugquma isandi se-Ra 24.5dB (ilinganiswe kuluhlu lwamaza e-125-4000Hz)
Qaphela: Iinkcukacha zephaneli yeacoustic evavanyiweyo zezi
Iphaneli ye-acoustic (ipleyiti ye-aluminium yogwebu) ubukhulu be-8mm, ubukhulu bomoya we-100mm, i-backing plate (ipleyiti yensimbi yombala) ubukhulu be-0.5mm, isakhiwo esihlangeneyo.
